php - Multiple Image Upload only uploading one image in Symfony 3? -

i'm building function upload multiple images our website, , far have upload form:

<?php namespace tyson\adminbundle\form;  use doctrine\orm\entityrepository; use symfony\component\form\abstracttype; use symfony\component\form\formbuilderinterface; use symfony\component\form\extension\core\type\submittype;  use symfony\component\form\extension\core\type\filetype; use symfony\component\form\extension\core\type\integertype;  class iutype extends abstracttype {      public function buildform(formbuilderinterface $builder, array $options)     {          $builder->add('id', integertype::class);         $builder->add('image', filetype::class, array(             'attr' => array(                 'multiple' => 'true',                 'data_class' => null             )         ));     }      public function getname()     {         return 'iu';     }  } 

this displayed on twig file this:

  <div class="tabs-panel" id="panel3v">       {{ form_start(iu,{action:path('admin_upload-images')}) }}        <div class="row">           <div class="small-3 medium-3 large-3 columns field-label">               <label>image id</label>           </div>           <div class="small-9 medium-9 large-9 columns">               {{ form_widget(iu.id) }}               {{ form_errors(iu.id) }}           </div>       </div>        <div class="row">           <div class="small-3 medium-3 large-3 columns field-label">               <label>image upload</label>           </div>           <div class="small-9 medium-9 large-9 columns">               {{ form_widget(iu.image) }}               {{ form_errors(iu.image) }}           </div>       </div>        <div class="row">           <div class="small-6 medium-6 large-6 columns">               <button type="submit" class="button" id="savebtn">save changes</button>           </div>       </div>        {{ form_end(iu) }}   </div> 

when submitted, during testing, i'm outputting handed controller form. output:

[files] => symfony\component\httpfoundation\filebag object     (         [parameters:protected] => array             (                 [iu] => array                     (                         [image] => symfony\component\httpfoundation\file\uploadedfile object                             (                                 [test:symfony\component\httpfoundation\file\uploadedfile:private] =>                                  [originalname:symfony\component\httpfoundation\file\uploadedfile:private] => cny8drqxyaaoaaw.jpg                                 [mimetype:symfony\component\httpfoundation\file\uploadedfile:private] => image/jpeg                                 [size:symfony\component\httpfoundation\file\uploadedfile:private] => 35164                                 [error:symfony\component\httpfoundation\file\uploadedfile:private] => 0                                 [pathname:splfileinfo:private] => /tmp/phpibzuvw                                 [filename:splfileinfo:private] => phpibzuvw                             )                      )              ) 

i select 1 image, or 100 images, , still form passing me 1 image before controller else.

for reference, code controller far:

<?php  namespace tyson\adminbundle\controller;  use symfony\bundle\frameworkbundle\controller\controller; use symfony\component\security\core\securitycontext; use symfony\component\security\core\user\userinterface;  use tyson\corebundle\entity\images;  use symfony\component\httpfoundation\request; use symfony\component\httpfoundation\cookie; use symfony\component\httpfoundation\session\session; use symfony\component\form\form; use symfony\component\httpfoundation\response; use symfony\component\httpfoundation\redirectresponse; use symfony\component\httpfoundation\jsonresponse; use symfony\component\filesystem\filesystem; use symfony\component\filesystem\exception\ioexceptioninterface;  use symfony\component\httpfoundation\file\uploadedfile;  class uploadcontroller extends controller {     public function uploadimagesaction(request $request)     {          $fs = new filesystem();          $dm = $this->getdoctrine()->getmanager();          $dir = '/var/www/html/tyson/web/uploads/images/';          $request = $this->get('request_stack')->getcurrentrequest();          $formdet = $request->request->get('iu');         $imgid = $formdet['id'];          $folderpath = '/var/www/html/tyson/web/uploads/images/'.$imgid;         $imgdirectory = '/var/www/html/tyson/web/uploads/images/'.$imgid.'/';          $foldercheck = $fs->exists($folderpath);          print_r($request);         die();      }  } 

i'd imagine file output should contain more 1 image controller (as form submitted once, not repeatedly), doing wrong happen?

same problem form me

          $builder->add('files', filetype::class, array('required' => false,             'mapped' => false,             'attr' => array(                 'multiple' => true             ),         ));  

only 1 file submitted. no solutions me now, add [] javascript upload name.
